    • Provided is a short-circuit isolator capable of earlier detection of recovery from short circuit of a disconnected line and reconnecting the line. The short-circuit isolator includes: a switch for switching a connection state between a primary signal line and a secondary signal line; a short-circuit monitor circuit which is connected to a primary wiring of the switch through a resistor as a current limiting section and connected to a secondary wiring of the switch, for detecting short circuit when a voltage of the secondary signal line is lower than a short-circuit detection threshold and detecting recovery from the short circuit when the voltage of the secondary signal line is higher than a short-circuit recovery threshold which is a voltage value lower than the short-circuit detection threshold after the short circuit is detected; and a switch control section for turning off the switch when the short circuit is detected by the short-circuit monitor circuit and turning on the switch when the recovery from the short circuit is detected by the short-circuit monitor circuit.
    • 提供了一种短路隔离器,能够较早地检测到断开的线路的短路恢复并重新连接线路。 短路隔离器包括:用于切换主信号线和辅助信号线之间的连接状态的开关; 短路监视电路,其通过电阻器作为限流部分连接到开关的一次布线,并连接到开关的次级布线,用于在二次信号线的电压低于 短路检测阈值,当二次信号线的电压高于在检测到短路后的短路检测阈值以下的电压值的短路恢复阈值时,从短路检测恢复; 以及开关控制部分,当短路监视电路检测到短路时,通过短路监视电路检测到短路恢复时,开关断开。
